Sorry if this question has been asked and answered else where. If it has I couldn't find it.
I recently started using a capo because I'm learning to play and sing a song that is written way too low for my vocal range. When I place the capo at the fifth fret, I need to re-tune. It's a Kyser clamping type capo. I place it in the middle of the two frets. The closer I put it to the fret I'm capoing the more out of tune the guitar becomes. Is it okay to re-tune with the capo in place? Will it damage the frets? Would a different type of capo not cause this? The Kyser clamps pretty tight.
